Overview
motivation
- There are OWL validation services mainly used for ontology validation, not much attention has been paid on OWL instances.
- different users have different requirements and focus on instance data, in particular, OO programmer require more strict checking than OWL semantics.
- There are a lot best-practice suggestions that prevent potential mistakes, while these suggestions are beyond OWL semantics.
- PML tools require instance data validation before they can process online PML instance data
motivating examples
- When both Joe and Bob are asserted as biological father of Alice, OWL reasoners will keep silent unless they know that Joe and Bob different.
- When forgot annotate longitude information when publishing an individual of GPS coordinate class, OWL reasoners will keep silent.
- When Joe, a person, mistakenly has a property foaf:member which requires foaf:Group as its domain, OWL reasoners will keep silent unless the disjoint relation between person and group has been asserted in FOAF ontology
Research
OWL Instance-data Evaluation
- we focus on issues caused by OWL instance data
- we focus on data on the Web
- We identified potential issues in OWL instance data
- We implemented a prototype using SPARQL, see http://onto.rpi.edu/demo/oie
- We developed formal semantics (integrity constraint) for this problem using auto-epistemic description logics
- We are exploring logical programing solution to this problem.
PML Validator
- We evaluate our research result in real world applications - PML
- We use PML Validator to check PML instance data and ensure it can be loaded by conventional structured data browser, e.g. ProbeIt and IWBrowser.
